Don't ever call the European wool carder bee (Anthidium manicatum) a slow poke. It's not "as fast as a speeding bullet" (Superman), but close.
The males, quite territorial, chase away other pollinators, including honey bees, sweat bees and butterflies.
The European wool carder bee gets it name from the fact that females collect or "card" leaf fuzz for their nests. Today we watched the bees sip nectar from our catmint blossoms and mate.
If you've never seen them in California, that's because they haven't been here that long. Originating from Europe, these bees became established in New York in 1963, and began spreading west. Bee scientists first recorded them in California (Sunnyvale) in 2007.
Like to attract them to your yard? Plant lamb's ear (Stachys byzantia) and catmint (Nepeta).

A day in the life of a single worker bee...
A honey bee tumbles off the flowering catmint (Nepeta) and struggles to right herself.
Her wings tattered, her body battered, she does not buzz away.
Perhaps she is approaching the end of her six-week lifespan--three weeks working inside the hive and three weeks working outside the hive. Bee scientists say that worker bees literally work themselves to death.
As a forager, she likely made about 40 trips a day gathering nectar and pollen. Forty trips a day. It's like going to the grocery store 40 times a day. Oops, forgot something. Got to return to the store.
Bees can forage from a distance of up 5 miles away from their colony, according to Extension apiculturist Eric Mussen of the UC Davis Department of Entomology.
She's just one bee of about 60,000 in the colony. And now, she will not return. She may have eaten something she shouldn't have or may have an intestinal infection, surmised Mussen.
Or maybe she was poisoned by a pesticide, snagged by a bird, bitten by a spider, or ravaged by Varroa mites.
Still, seeing a honey bee tumble off a blossom and die is something we humans rarely observe.
Meanwhile, her sisters keep working the blossoms, tasks needed to keep the colony alive. Back at the hive, the queen bee is busily laying about 2000 eggs a day to replace all the adult bees who die every day.

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be
--Paul McCartney
When Paul McCartney of The Beatles wrote "Let It Be," released in 1970, he wasn't writing about honey bees.
No, he was actually recounting what his mother (who died when he was 14) told him in a dream. In real life, McCartney and his fellow musicians were clashing. In the dream, his mother soothed him: "It will be all right, just let it be."
But sometimes you just can't let it be.
Or bee.
We recently encountered an industrious honey bee nectaring catmint (Nepeta) in our yard. A gorgeous bee. Here she is buzzing from flower to flower, sipping nectar here, sipping nectar there, and then she makes a huge mistake: she buzzes right into the web of a cunning garden spider. As she struggles to free herself, the spider begins approaching her.
We captured the spider/honey bee scenario with our digital camera--four frames in one second--and then released her.
Not going to be a wrap today.
We let her "bee."

if you're growing plants in the mint family, Lamiaceae--you know, the plants with the square stalks and opposite leaves--you may see a very tiny reddish-orange visitor.
It's so tiny that it's smaller than the leaf of a catmint (Nepeta). Its wing span is probably about 10 to 15 millimeters.
This little critter (below) is a California Pyrausta Moth (Pyrausta californicalis), as identified by butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis. Pyrausta is a genus of moths in the Crambidae family.
We spotted this one Saturday morning in our yard, foraging in the catmint. This is one moth you'll see during the day!
"Pyrausta californicalis is a native feeder in the mint family, which is often quite common on cultivated exotic mints, including spearmint, peppermint, etc.," Shapiro said.
In fact, Shapiro found the mint moth in his own garden in Davis for two decades "until I took the spearmint out."
And, it occurs on introduced mint in his Gates Canyon study site near Vacaville, Calif.

The wool carder bees (Anthidium manicatum), so named because the females collect or "card" plant fuzz for their nests, move quickly. The males, more aggressive and very territorial, move even faster.
The wool carder bee is an Old World bee introduced into the United States (New York) in 1963. It was first discovered in California (Sunnyvale) in 2007.
Today we spotted one in our Vacaville yard that didn't seem to be in much of a hurry.
In fact, it sidled up to the catmint (Nepeta) and appeared to be having a conversation. No, not with an empty chair. With a mint leaf.
Girl bee?
No, said native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and one of the instructors at the annual Bee Course at the Southwestern Research Station, Portal, Ariz.; this year's course takes place Sept. 10-20.)
"This one is a boy bee," Thorp said. "Note the prominent golden fringe hairs along the side of the abdomen and the edge of the tooth-like processes at the tip of the abdomen. Also the lower part of the face (the clypeus) is mostly yellow."
So there you have it, a boy bee!
I'm still wondering why he wasn't body-slamming the honey bees and engaging in other aggressive and territorial escapades.
